How are magnetic nanoparticles of CoFe 2 O 4 prepared?

How are magnetic nanoparticles of CoFe 2 O 4 prepared?

In this study, magnetic nanoparticles CoFe 2 O 4 have been prepared by three different methods; combustion, coprecipitation, and precipitation and their sizes have been compared. As these nanoparticles show magnetic behaviors, their magnetizations have also been measured and compared.

How is coprecipitation used in the synthesis of cobalt ferrite?

Coprecipitation route is a cheap and simple method, in which the control of size and size distribution is obtained by controlling the relative rates of nucleation and growth during the synthesis process.

How are nanoparticles used to make ferrites?

Large-scale applications of ferrites with small particles and tailoring of specific properties have prompted the development of widely used chemical methods, including combustion, coprecipitation, sol-gel, mechanical alloying and precipitation for the fabrication of stoichiometric and chemically pure spinel ferrite nanoparticles.

Is the precipitation method the same as coprecipitation?

The precipitation method (stober synthesis), same as coprecipitation is simple and does not need any mechanical apparatus. This method is usually used to synthesize core–shell nanoparticles and its only difference with coprecipitation method is in the length of time which is needed to put shell and finally dialyzing the particles [7], [8].

What can CofE 2 O 4 be used for?

There are promising applications for CoFe 2 O 4 in different fields such as drug delivery, hyperthermia, magnetic resonance imaging (MRI), magneto-sensitive, and tissue imaging. Also, this material is used in environmentally friendly fields.

How are nanoparticles of cobalt ferrite synthesized?

In this work the cobalt ferrite (CoFe 2 O 4) nanoparticles are synthesized using three different methods; combustion, coprecipitation, and precipitation. Size, structural, and magnetic properties were determined and compared using X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM).

Why are cobalt and iron oxides magnets?

Cobalt and iron oxides are known as highly attractive magnetic materials among other oxides due to their specific properties and low-cost production.
